mine shoots the 100 tSX or TTSX into the same group over 46.5 grains of H4350 with federal 210M primers, winchester cases, at 2.815 OAL for both bullets. You may have to play with your OAL but it shoots fine in my Kimber. Its accurate with a routine 1 inch group and it kills deer just fine.
with the TSX I dont see any point in going to a heavier bullet for the roberts.
